Drive
analyses include plots of historical and predicted cumulative and
incremental reservoir drive indices vs. time, aquifer and gas cap sweep
efficiency vs. time, and reservoir fluid volumes vs. time. These
analyses indicate the relative strengths and efficiencies of reservoir
drive mechanisms and how they change with time. In water-drive gas
reservoirs, for example, these drive analyses can quantify the recovery
benefits of increasing voidage rates to minimize cumulative aquifer
influx and reservoir pressure at abandonment. Recovery Analyses
Recovery analyses include plots of reservoir pressure vs. recovery, WOR
vs. recovery, and recovery vs. aquifer influx and injection. These
analyses are particularly useful for surveillance of oil reservoirs
produced under natural water drive or during water-flood operations.
